Applicators
To provide the best hyperthermia treatment for every tumor size and shape, three different applicators are available for local hyperthermia therapy.
The 24-antenna applicator
was developed specifically for treatment of chest wall recurrence. 24 spiral antennas are mounted on a rectangular, flexible silicone carrier and are connected to an 8-channel microwave generator. This allows the applicator not only to be adjusted to fit the specific body and tumor contour – specifically, the chest wall tumor size and shape – but also permits the 24 spiral antennas to be activated selectively in order to achieve a tumor-specific temperature distribution.

The MA-151 waveguide applicator
is used for hyperthermia treatment of small lesions in the head/neck area. The slim shape of this applicator enables it to reach poorly accessible tumors.

The plate-shaped spiral applicators
are suitable for treatment of tumor lesions close to the skin‘s surface. Each spiral antenna can be activated individually. This permits the temperature distribution to be targeted precisely to the individual tumor characteristics.
Three applicator versions ensure optimal matching to the tumor contour and region of the body: The SA-812 has a diameter of 12 cm and is equipped with eight spiral antennas. Within its diameter of 10 cm, the SA-510 contains five spiral antennas. The SA-308, with its three spiral antennas and a diameter of 8 cm, is appropriate for small lesions. All spiral applicators are characterized by their low inherent weight and are manufactured from a transparent material, allowing simple positioning.
High-frequency generator
The BSD 500 Microwave Hyperthermia System features a 915 MHz generator with eight channels, with phase and amplitude of each adjustable individually. Using the three-way splitter in the eight-channel generator, up to 24 antennas can be powered. The eight signals from the individual channels (each capable of delivering up to 50 watts) can be combined to provide a total output of up to 400 watts.
Provides ease of operation
The BSD 500 System is a so-called roll-around, plug-in unit. As with an ultrasound unit, it can be moved to any room and operated without shielding. With the aid of an additional module, the system is also suitable for administering interstitial hyperthermia in conjunction with brachytherapy.
